Legal claims defining the scope of protection. Each claim is shown in both the original legal language and a plain English translation.
1. A receiving device for receiving files via a first logical channel from a transmitting device, the receiving device comprising: a receiver to receive, via a second logical channel, play parameters about a file that is being or is to be received, via the first logical channel, the play parameters being generated by the transmitting device and including (i) information about a play rate for the file, (ii) information corresponding to a delay time for the file, and (iii) information about a probability that the receiving device can achieve the play rate for the file; and an evaluating device to receive the play parameters and to determine a start time to begin play back of the file based on the play parameters, so that the file can be played back while the file is being received by the receiving device, wherein the play parameters are received prior to the file being received by the receiving device.
A receiving device gets files over one channel and pre-fetches "play parameters" about the file via a second channel *before* it starts receiving the actual file. These parameters, created by the transmitting device, include the file's playback rate, a delay time (offset), and the likelihood the receiving device can maintain that playback rate. An evaluation component uses these parameters to decide when to *start* playing the file so playback can begin while the file is still being downloaded.
2. The receiving device of claim 1 , further comprising: an intermediate storage device to receive the file and to provide a data stream of the file at the determined start time.
The receiving device described above includes an intermediate storage (buffer) to store the incoming file data. After the start time is calculated using play parameters about a file that is being or is to be received, via the first logical channel, the play parameters being generated by the transmitting device and including (i) information about a play rate for the file, (ii) information corresponding to a delay time for the file, and (iii) information about a probability that the receiving device can achieve the play rate for the file the file is then provided as a data stream from the buffer at that specific time.
3. The receiving device of claim 2 , wherein the intermediate storage device delivers the data stream at a constant bit rate.
The receiving device with the intermediate storage (buffer), described above, where the start time is calculated using play parameters about a file that is being or is to be received, via the first logical channel, the play parameters being generated by the transmitting device and including (i) information about a play rate for the file, (ii) information corresponding to a delay time for the file, and (iii) information about a probability that the receiving device can achieve the play rate for the file, delivers the buffered file data as a constant bitrate stream.
4. The receiving device of claim 1 , wherein the evaluating device determines the start time based further on reception conditions of the first logical channel and on file characteristics of the file.
In the receiving device, where the start time is calculated using play parameters about a file that is being or is to be received, via the first logical channel, the play parameters being generated by the transmitting device and including (i) information about a play rate for the file, (ii) information corresponding to a delay time for the file, and (iii) information about a probability that the receiving device can achieve the play rate for the file, the calculated start time also considers current channel conditions and characteristics of the file itself (e.g., size, encoding).
5. The receiving device of claim 4 , wherein the reception conditions of the first logical channel comprise a reception rate of data of the first logical channel.
This describes a receiving device that determines when to start playing a file it's currently downloading. The device first receives "play parameters" from a transmitting device via a separate control channel, *before* the file data itself arrives. These parameters specify the file's intended play rate, any associated delay, and the probability that the receiving device can actually maintain that play rate. To calculate the optimal playback start time, the device utilizes these initial play parameters. Critically, it *also* incorporates information about its current reception conditions on the primary data channel (the channel through which the file is being received) and characteristics of the file itself. For example, a key reception condition considered when calculating the start time is the actual data reception rate of the primary channel, ensuring playback begins smoothly while the file download is still in progress.
